PersistenceServiceImpl
The class detailed in Listing D.9 implements the JNLP 1.0 runtime persistence services by
means of files saved on the local filesystem. All these files are rooted under the “
.jnlpImpl
”
directory under the user home. On Windows machines such a directory is located in the
Windows
system directory and it is created on-the-fly.
C
AUTION
The current implementation is not compatible with other JNLP Clients' implementa-
tions. This class cannot read data saved via the JNLP runtime API by another JNLP
Client, because it relies on a different, file-based caching mechanism.
